Strategic Circular Economy in Construction: Case Study in Sardinia, Italy
Publication: Journal of Urban Planning and Development
Volume 147, Issue 4
Abstract
The paper tackles a topic related to the use of prime material and recycled materials in construction, in the framework of the circular economy, where recycled aggregates can be considered, in part or even totally, as second prime materials for the construction sector. In particular, the authors describe the main phases of the MEISAR project, developing a circular cluster territorial model so that the quantity of recyclable materials can be estimated and geolocalized in the most appropriate processing plant, as well as assessing the potential market. In the study we combine spatial planning problems and industrial location factors of natural and recycled aggregates and concrete production plants through the geospatial representation of the MEISAR map. The closed market of Sardinia is analyzed and, in particular, the case study of the new soccer stadium in Cagliari, which involves the demolition of the existing stadium that will represent a source of “secondary” raw materials for the construction of the new stadium designed by the consortium Sportium.

This study was supported by the research grant for the project “Investigating the relationships between knowledge-building and design and decision-making in spatial planning with geodesign” funded by Fondazione di Sardegna (2018).
The paper is the result of the joint reflections and aims of the authors. However, the idea, conceptualization, organization, and structure of the paper are attributed to Ginevra Balletto. Giuseppe Borruso focused on the geographical implications and performed the geographical elaborations. Alessandra Milesi and Giovanni Mei collected data and organized the geographical database and performed the background and literature review.
